What can I do about my moms habits?

My life is mad crazy its going to take long to type this and I wanna thank you so much for taking the time to read it.Okay my mom and dad got married in 1996 and had me in 1997 im thirteen.Already when I was born everything was wrong.My dad was drunk all the time when he came home from staying out at bars evernight..and my mom would dread him coming home.One day he was so drunk he punched her in the face and she had a black eye.Now throughout my life my parents have never gotten along.I remember many times I was having panic attacks because of all the things my dad would threaten to do or all the things that were being said right in front of a minor (myself)So in Sept.2009 they finally got separated I was devastated back then.Then my dad came back 3 times and it didnt work out he left twice because he said my mom and I fight and he left a third time because he said the house wasnt clean.Now they are separated for good.And im happy actually I just hope my dad keeps up the money giving because he has to..and I dont want it to be like past separations..I will barely see my dad in fact he and I dont talk because I called him insane a couple weeks ago in which his case that is SO true.My dad has always trying to give me everything he didnt have when he was little..but now that he is gone my mom is slacking off..she sleeps when I come home everyday..she doesnt clean..doesnt get things done..talks to gay friends on the phone constantly..drinks once a week..and really is getting on my nerves.
